Frequently Asked Questions
Q: Are USA Standard Gear parts strong enough for diesel trucks?
A: Yes. While they’re more affordable than premium brands, USA Standard Gear components are engineered for daily-driven diesel trucks, moderate towing, and off-road use.
Q: What's the difference between USA Standard and Yukon Gear?
A: USA Standard offers cost-effective alternatives with solid performance, while Yukon is their high-performance premium line. Both are backed by the same parent company.
Q: Do I need a master install kit when changing ring & pinion gears?
A: Absolutely. A complete master install kit ensures proper fitment, preload, and sealing when setting up new gears — don’t skip it.
